◆What is Super Alloy Coating◆ Super Alloy Coating is a surface treatment that covers soft substrates such as plastics and rubber, as well as lightweight metals like aluminum and thin sheets, with an alloy that has a hardness of Hv 600 or higher, while also providing flexibility. It effectively prevents dirt on various manufacturing equipment and components, reduces maintenance tasks such as the peeling of adhesive materials, and exhibits excellent mechanical strength and durability. The surface of the coating has rounded protrusions, which minimizes scratching of contact objects. Additionally, despite being a metal coating, it has the ability to conform to slight bends and can accommodate curved surfaces. It allows for excellent release properties from adhesive materials and strength while maintaining the flexibility of the processed material. 【Features】 ■ Non-adhesive convex surface formation ■ Alloy coating with Hv hardness of 600 ■ Excellent mechanical strength and durability ■ Minimization of scratches on contact objects ■ Processable with various materials *For more details, please refer to the PDF document or feel free to contact us.

**Coating for Improved Rust and Corrosion Resistance** Stainless steel is inherently a material with excellent corrosion resistance, but if you want to further enhance its rust and corrosion resistance, it is necessary to apply a coating. Generally, coatings are applied using paints such as epoxy resin or polyurethane. These paints are known for their durability and weather resistance, providing high rust prevention effectiveness even in environments with corrosive gases or saltwater. For use in even harsher environments, it is also possible to coat with highly corrosion-resistant fluoropolymer resins. For example, resins like PFA and PTFE excel in chemical resistance and can be used in environments with strong acids or strong alkalis. If you are considering improving the corrosion resistance of stainless steel pipes used in harsh environments, we recommend fluoropolymer coating. *For more details on fluoropolymer coatings, please refer to the materials or feel free to contact us.*

Teflon is a trademark of Chemours and refers to fluoropolymer. Fluoropolymers include types such as PTFE, PFA, and FEP, but currently, the use of fluoropolymers like PTFE, PFA, and FEP is not regulated in Japan. On the other hand, within the EU, regulatory proposals are being considered to minimize the emissions of PFAS. The following substances are also mentioned as targets: - Fluorinated surface treatment agents: water and oil repellents, release agents, fluoropolymer-containing coatings, etc. - Coatings: PTFE, PFA, FEP, ETFE, and other fluoropolymers (for applications such as corrosion lining, non-stick, lubrication, etc.) - Molding and processed products: PTFE, PFA, FEP, ETFE, and other fluoropolymers (such as lining sheets, fabric sheets, etc.) - Fluorinated surfactants, fluorinated oils, low molecular weight PTFE, fluorinated molding aids, etc. The regulatory proposals include fluoropolymers, which are considered to be extremely stable and pose no toxicological or environmental concerns.

In cases where more reliable hardness and durability are required, wet processes such as plating may be more effective than fluoropolymer coatings. Additionally, gold and silver plating may be applied not only for functional purposes but also for decorative purposes. Yoshida SKT accommodates various plating processes. *For more details, please refer to the catalog or contact us directly.*

To prevent noise in production sites and to reduce labor and weight of equipment, switching from metal to lightweight and high-strength CFRP materials is effective. However, changing materials is not always beneficial. In actual production environments, there may be challenges such as, "Once we switched to CFRP rollers, we could no longer perform the surface treatment to prevent adhesion." ■ With Yoshida SKT, improvements can be made even with CFRP rolls and jigs through coating. 【Effects of Coating on CFRP Rolls】 - Adhesive adhesion measures can be implemented, making cleaning easier. - No adhesive residue, eliminating negative impacts on products. - No line stoppages, improving production efficiency. ◆ Coatings Used ◆ ■ Super CTT Coating (Silicone-based contact area reduction coating) 【Features】 - Release properties - Cushioning properties - Tackiness ■ Super Alloy Coating (Flexible alloy coating) 【Features】 - Release properties - Slipperiness - Wear resistance; hardness: HV600 *For more details, please download the PDF or contact us.
